Input Breaker Rating for Power Systems

[thomasdeji (Adedeji Thomas)]

Could you kindly advise what’s the Input breaker rating you will recommend for the following system capacity:

1. 3 Phase 180kVA Quattro Inverter plus 150kW AC Coupled system
2. 3 Phase 90kVA Quattro Inverter plus 75kW AC Coupled system
3. 3 Phase 60kVA Quattro Inverter plus 45kW AC Coupled system
4. 3 Phase 45kVA Quattro Inverter plus 30kW AC Coupled system

Will appreciate you share calculation procedure to size input breaker rating for both 3 Phase and Single Phase power system

Thank you.

Not really the place for System Design

Long, multifaceted issues involving system design, multiple run on questions with very specific installation and nuanced details are not really well suited for the structure of the community. It is best to have a single question with a clear title per post. More complex enquires are best be directed towards your distributor.

This is best directed to the local distribution centre.
Not something that should be discussed on the forums.
Too big too much risk involved.

This expecially requires knowlege that people have trianed for and charge for to make a living. Has too many other factors to consider just one off the top of my head is operating temperature. Therefore is unfair to ask for free.
